PHOTOGRAPH-PRINTING APPARATUS.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, HERMAN SHArIRo, a citizen of the United States, residing. at Cleveland, in the county of C-uyahoga and State of Ohio, have invented a certain new and useful Improvement in Photograph- Printing Apparatus, of which the following is a full, clear, and exact description.

This improvement in photographic printing apparatus is designed to rapidly produce a multiplicity of prints from a film negative. To accomplish this result accord ing to this invention the film negative is made into the form of an endless belt which is caused to continuously travel over suitable guide rollers through a prescribed path around a slotted casing in which is a light, and at the same time a plurality ofstrips of sensitized paper is caused to travel in surface contact with certain parts of the film adjacent theslots in the light inclosing casing. I

The invention consists in the construction and combination of parts shown in the drawing and hereinafter described and pointed out definitely in the appended claims.

In the drawings, Figure 1 is an end elevation of the apparatus; Fig. 2 is a sectional side elevation on line 2-2 on F ig. 1, and Fig. 3 is a sectional view on line 3-3 on Fig. 1.

The apparatus as shown in the drawing is designed for simultaneously printing four pictures during each complete revolution of the endless film belt. It is obvious, however, that the apparatus could be organized to print more or less pictures at the same time by properly disposing the guiding rollers and properly slotting the light inclosing casing.

Referring to the parts by reference characters, 10 represents an endless photographic film, on which is the picture or pictures to be reproduced. 11, 12, 13 and 14 represent four parallel rollers arranged symmetrically around and close to a light inclosing casing 15 in which are four longitudinal slots 16 adjacent the several roll-v ers. These slots are of variable width made so by the movable shutters 17 in order that the intensity of the light may be regulated in accordance with the thickness of the film 10. These shutters may be formed with inclined slots 17 through which pass pins 15 carried by the light casing, so that by the endwise movement of these shutters they will be caused to move toward or from each other. These shutters are formed with the flanges 17 on their adjacent edges,which flanges at their outer edges come close to the surface of the film, so as to substantially confine the action of the light to the narrow space thereon which for the time being is between these flanges. The light employed in the casing must obviously be one that is equally operative and effective at the four light slots. A Cooper-Hewitt light is suitable for this purpose. These rollers 11 to 14 are the film driving rollers. Each has on its end a pinion 18 that meshes with a driven gear 19.

Intermediate of the four driven rollers are four idler rollers 20, 21, 22, 23, which are adjustable toward and from the light casing 15. These rollers are mounted in journal boxes 24 and the journal boxes are mounted in guideways 25. Each box is independently movable in its guideway by an adjusting screw 26. By the adjustment of one or more of these idler rollers the endless film belt may be made sufliciently tight regardless of its length, within the limits of the machine. A roll 40 of sensitized paper 41 is associated with each of the driving rollers 11, 12, 13, 14. It is rotatably mounted in a suitable position relative to its associated driving roll, so that the paper may be drawn from the paper roll and passed, in surface contact with the film belt, between the same and the associated driving roll. As the film and each strip of paper pass along, in surface contact between the driving roll and the light easing, past the associated slot in the latter, the picture on the film will be progressively printed on the paper. Each paper strip after it passes the printing position goes to and is secured to a reel 43 which embraces a motor driven shaft 44 with which the reel has such frictional engagement as will permit relative slippage, but will cause the reel to turn fast enough to wind up the paper.

Associated with each of the rolls 11, 12,

in contact with each of thosestrips ofvsen-V sitized paper. The result will be that the entire-picture onthe filnibelt will beprinti5 edon each of tliosestrips of sensitized paper during each revolution of the film belt. In

other words, four pictures are being printed atthe same tinie and the printing of pietures on eaehsensitized paper stripis being 2 repeated indefinitely each timeithe film belt completes its revolution.

While the described apparatus embodies thcinventionin thebcst form, as I believe, forthe rapid reproduction of the same pic- 3 ture or .group of: pictures, it will be ob- (vious that any unit of the apparatus may be employed. to continuously and progressively- ,print on a strip 7 of sensitized paper any series'oi pictures on aphoto gi'aphicfilm. 7 One hasonly to cause the pa per and film to move at the PIQPBI3 rate in surface contact with each other-between one 01 the rolls 11, 12, 13, 1e, pastand closeto-the slottedlight containingcasing so as-to come within theinfiuence as described of the light rays emitted from-the adjacent. slot of said casing. ,7
